RESUMEN

BACKGROUND: Hemorrhoidal disease (HD) significantly impacts patients' quality of life. This study aimed to evaluate the effectiveness of preoperative treatment with the micronized purified flavonoid fraction (MPFF) and a sucralfate-based rectal ointment in managing HD symptoms and reducing interventions. METHODS: A prospective quasi-experimental study including consecutive cases and controls matched on the basis of sex was performed in a tertiary referral center. Cases received systemic and local therapy for HD, consisting of a rectal ointment containing 3% sucralfate and herbal extracts plus MPFF, in addition to conservative therapy, while controls received conservative therapy alone. The hemorrhoidal disease symptom score (HDSS), the Short Health Scale for HD (SHS-HD) score, and the Vaizey Incontinence Score were used to evaluate symptoms severity and their impact on quality of life and continence. Intervention requirements were assessed at baseline (T0) and after 60 days of treatment (T1). RESULTS: Between January and December 2023, a total of 98 patients were assessed for eligibility. After exclusions, 56 patients were enrolled, with 28 in each group. Significant improvements were observed in HD symptom scores from T0 to T1: the intervention group showed a mean change in HDSS of -9 [95% confidence interval (CI) -10 to -8], and the control group showed no significant change (mean change of 0; 95% CI -1.5 to 0). At T1, a higher proportion of patients in the intervention group underwent less invasive interventions compared with controls (18% versus 11%). Age, treatment group, and baseline symptom severity significantly predicted post-treatment symptom scores. CONCLUSIONS: In our study the preoperative treatment with MPFF and a sucralfate-based rectal ointment demonstrated clinical benefits in managing HD symptoms and reducing interventions. Further prospective trials are warranted to confirm and explore additional therapeutic strategies.

RESUMEN

Corneal abrasion is a frequent complication in critically ill, intubated patients, potentially leading to visual impairment. This study compares the efficacy of three ocular care methods in preventing corneal abrasion among this vulnerable population. We conducted a randomized controlled trial involving 156 intubated adult patients admitted to the ICU. Participants were randomly allocated to one of three intervention groups (n = 52 per group): (1) polyethylene cover only, (2) polyethylene cover with artificial tear drops, and (3) polyethylene cover with Lubratex eye ointment. One eye per patient was randomly assigned as the control, receiving standard ICU eye care. Daily assessments over five days included a standardized dryness and corneal abrasion checklist, graded strip evaluation of eye dryness, and documentation of corneal abrasion incidence. Data were analyzed using descriptive and inferential statistics (SPSS-18). The incidence of corneal abrasion was significantly lower in the group receiving polyethylene cover with Lubratex eye ointment (4%) compared to the polyethylene cover with artificial tears group (36%, p < 0.001) and the polyethylene cover only group (60%, p < 0.001). The combined application of a polyethylene cover with Lubratex eye ointment effectively prevents corneal abrasion in intubated ICU patients. This method demonstrates superior efficacy compared to polyethylene covers used alone or with artificial tears. We recommend its implementation as standard practice for corneal abrasion prophylaxis in this high-risk population.Trial Registration.

RESUMEN

Retinoids are known to improve the condition of the skin. Transepithelial transport of sodium and chloride ions is important for proper skin function. So far, the effect of applying vitamin A preparations to the skin on ion transport has not been evaluated. In the study, electrophysiological parameters, including transepithelial electric potential (PD) and transepithelial resistance (R), of rabbit skin specimens after 24 h exposure to retinol ointment (800 mass units/g) were measured in a modified Ussing chamber. The R of the fragments incubated with retinol was significantly different than that of the control skin samples incubated in iso-osmotic Ringer solution. For the controls, the PD values were negative, whereas the retinol-treated specimens revealed positive PD values. Mechanical-chemical stimulation with the use of inhibitors of the transport of sodium (amiloride) or chloride (bumetanide) ions revealed specific changes in the maximal and minimal PD values measured for the retinol-treated samples. Retinol was shown to slightly modify the transport pathways of sodium and chloride ions. In particular, an intensification of the chloride ion secretion from keratinocytes was observed. The proposed action may contribute to deep hydration and increase skin tightness, limiting the action of other substances on its surface.

RESUMEN

BACKGROUND AND OBJECTIVE: Episiotomy is one of the most commonly performed procedures in obstetrics. complications of episiotomy are pain, bleeding, infection, pain in the sitting position, and difficulty in taking care of the baby. This study aimed to investigate the effect of Camellia sinensis ointment on perineal pain and episiotomy wound healing in primiparous women. METHODS: This triple-blinded randomized clinical trial was conducted on 60 primiparous women who were referred to the maternity ward of Al-Hadi hospital in Shoushtar and Ganjovian hospital in Dezful, Iran, from 2020 to 2021. Participants were randomly assigned into two groups of intervention (Camellia sinensis extract ointment) and control (placebo) with a follow-up of 14 days. REEDA scale (redness, edema, ecchymosis, discharge, and approximation) was used to measure wound healing and the Visual Analog Scale (VAS) was used to measure the pain intensity. RESULTS: There was no significant difference between two groups before intervention in terms of sociodemographic characteristics, pain intensity, and episiotomy wound status. Scores of pain intensity and wound healing reduced on days 7, 10, and 14 post-intervention in the intervention group compared to placebo. There was a significant decrease between the groups of intervention and control in terms of the mean score of pain intensity (VAS scale) on day 10 (1.33 ± 0.71, 1.77 ± 0.93) and day 14 (0.73 ± 0.74, 1.13 ± 0.81) post-intervention (P < 0.05). Also, on day 14 post-intervention, there was a significant decrease between the groups of intervention and control in terms of the mean score of episiotomy wound healing (REEDA index) (0.53 ± 0.77, 1.77 ± 1.46) (P < 0.05). The GLM test was applied for repeated measures. REEDA index and VAS scale changed during different times (time-variable) (p < .001). But, the studied groups (group variable) and the studied groups (interaction effect of group * time) did not affect the changes in the REEDA index (p = .292, p = .306) and VAS scale (p = .47) during different times. CONCLUSION: Our study showed that Camellia sinensis extract ointment has a small effect on the healing process and pain reduction of episiotomy wounds. to confirm its effect, a study with a larger sample size should be conducted. TRIAL REGISTRATION: This trial was registered in the Iranian Registry of Clinical Trials on 04/10/2019 with the IRCT ID: IRCT20190804044428N1. Participants were enrolled between 11 April 2020 and 20 January 2021. URL of registry: https://en.irct.ir/trial/41326.

RESUMEN

Generic medications contain the identical active ingredient in the same concentration as their branded counterparts and are administered in the same manner, aiming to deliver comparable efficacy, dosage, and clinical outcomes. Nevertheless, variations in additives and formulation processes, particularly noticeable in topical medications, can influence factors like ease of use and patient adherence. Therefore, in this study, we aimed to compare the rheological attributes of branded and generic injectable ointments, assessing disparities in formulation performance and their impact on patient care. Posterisan® Forte and Hemoporison® ointments were used as the branded and generic versions, respectively, and their viscosity, ductility, and viscoelastic properties were evaluated. Posterisan® Forte showcased enhanced spread ability, maintaining uniform flow characteristics across varying temperatures, whereas Hemoporison® displayed pronounced thixotropic properties and stiffness, suggesting potential benefits for applications necessitating reversible viscosity adjustments and heightened rigidity. Despite sharing identical additives, observable differences in physical characteristics highlight the necessity of understanding formulation traits, which could influence ointment behavior. Alterations in fluidity and viscosity may affect how patients perceive and apply the medication, potentially influencing treatment outcomes and the occurrence of adverse effects.

RESUMEN

BACKGROUND/AIM: Skin wound healing is a physiological process restoring the structural and functional integrity of injured skin. During this process, wound management preventing bacterial infection and complications is important for the regeneration of skin layers and adnexa, as well as the protective function of the skin. Therefore, the development of an effective ointment to promote wound healing without complications is beneficial. MATERIALS AND METHODS: This study developed Raepenol™ cream, comprising a base cream and natural compounds including paeonol, D-panthenol and extract of Centella asiatica, and assessed its therapeutic effect in wound healing. A rat model of skin wound healing and a mouse model of imiquimod-induced pruritus were employed. The effect of Raepenol™ cream was evaluated by wound size and histological analysis, including the integrity of skin structures and inflammatory response. RESULTS: Raepenol™ cream treatment effectively restored the structural integrity of the skin in rats, including wound closure, regeneration of skin adnexa, and reconstitution of collagen, comparable to commercial ointment. Additionally, Raepenol™ cream significantly suppressed pruritus by inhibiting mast cell infiltration or retention in the inflammatory site of mouse ears. CONCLUSION: Raepenol™ cream effectively promoted wound healing and relieved pruritus in animal models. These results suggest that it could be a promising option for wound care and pruritus relief, offering potential advantages over current ointments.

RESUMEN

Fungi are a source of a variety of secondary metabolites of importance in different areas of biotechnology. Several compounds have been characterized with antioxidant, antimicrobial, and anti-inflammatory activity from fungi of the division of the Ascomycota, among which is the species Daldinia eschscholtzii, an endophyte fungus of pantropical distribution. In this study, we evaluated the effect of an ointment made with D. eschscholtzii on the wound healing of BALB/c mice. The species was corroborated using a molecular marker Internal Transcribed Spacer (ITS1 and ITS4). The extracts and dust of the fungus were considered nontoxic as they caused a mortality of <15% in the nematode Panagrellus redivivus, and experimental ointments had no adverse effects on the skin of BALB/c mice. Wounds treated with the D. eschscholtzii ointments had 99.9-100% wound contraction after 17 days, which was similar to commercial healing (positive control). As such, the ointment of D. eschscholtzii is a natural alternative to improve wound healing.

RESUMEN

OBJECTIVES: To investigate if daily treatment with glyceryl trinitrate (GTN) ointment, over 24 weeks combined with a 12-week eccentric exercise programme is more effective for chronic mid-portion Achilles tendinopathy than placebo ointment and eccentric exercise. METHODS: This was a single-site randomised double-blind placebo-controlled trial at an acute hospital, Dublin, Ireland. Patients with chronic mid-portion Achilles tendinopathy were randomised to either 24 weeks of daily GTN ointment or placebo ointment. Both groups received an identical 12-week eccentric exercise programme. The primary outcome measure was the Victorian Institute of Sport Assessment-Achilles (VISA-A) questionnaire at 24 weeks, which measures pain, function and activity. Secondary outcomes included pain severity, self-reported physical function, calf muscle function, pressure pain thresholds and ultrasound changes. Statistical analyses were performed according to intention-to-treat principles. RESULTS: 76 patients (30 women; 46 men, mean age±SD, 45.6±8.2 years) were recruited for the trial. Significant improvements in VISA-A scores occurred in both groups at 6-week, 12-week and 24-week follow-up. The increase was not significantly different between groups, adjusted mean between-group difference from baseline to week 6, -1.33 (95% CI -6.96 to 4.31); week 12, -1.25 (95% CI -8.0 to 5.49) and week 24, -3.8 (95% CI -10.6 to 3.0); negative values favour GTN. There was no significant between-group difference in any of the secondary outcome measures at 6, 12 and 24 weeks. CONCLUSIONS: Adding daily GTN ointment over 24 weeks to a 12-week eccentric exercise programme did not improve pain, function and activity level in patients with chronic mid-portion Achilles tendinopathy when compared with placebo ointment.

RESUMEN

OBJECTIVE: To describe the clinical course and treatment of 3 dogs with peripheral vasopressor extravasation. CASE SERIES SUMMARY: Although vasopressor extravasation (VE) is a well-documented complication in human medicine, literature describing VE and its management in veterinary patients is sparse. VE increases patient morbidity by causing local tissue injury and necrosis. The gold standard treatment for VE, phentolamine, has been periodically limited in supply in human medicine and is not consistently available for use in veterinary medicine. An alternative protocol proposed for use in people with VE combines topical nitroglycerin application with subcutaneous terbutaline infiltration. In this report, a treatment protocol utilizing these therapies was used to treat 3 dogs with VE and secondary tissue injury. NEW OR UNIQUE INFORMATION PROVIDED: This report describes 3 cases of VE-induced tissue injury in dogs. In addition, this report describes the use of perivascular terbutaline infiltration and topical nitroglycerin application as therapeutic management for VE in dogs.

RESUMEN

Dapagliflozin is a pharmacological drug commonly used to manage type 2 diabetes by inhibiting the sodium-glucose cotransporter in the proximal renal tubules. The primary objective of this research was to develop a topical ointment formulation containing dapagliflozin and assess its efficacy in treating psoriasis using an imiquimod-induced psoriasis model. A total of 16 Swiss albino mice, with weights ranging from 24 to 30 grams, were allocated randomly into six groups, each group including ten animals. The study assessed the effects of various concentrations of dapagliflozin ointment on levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-8 (IL-8), IL-17, and IL-37, as well as on erythema, scaling, and epidermal thickness. Dapagliflozin ointment significantly reduced these cytokine levels and disease scores, indicating anti-psoriatic and anti-inflammatory properties. Therefore, when applied topically, dapagliflozin ointment had strong efficacy against imiquimod-induced psoriatic skin inflammation, suggesting its potential as a novel therapeutic option for psoriasis treatment.

RESUMEN

ABSTRACT: Perianal ulcers (PAUs) related to antihemorrhoidal product use have been recently reported in the literature through a few case reports. However, other etiologies of PAU must be ruled out, including infectious disease, inflammatory disease, malignancy, pressure injuries, radiotherapy, and other topical drugs. In this report, the authors describe two cases of PAUs due to an antihemorrhoidal ointment. In case 1, a 68-year-old woman with a history of hemorrhoids presented with PAUs after using an antihemorrhoidal ointment for 2 months. The ulcers were assessed through a histopathologic study and treated with calcium alginate dressings, with complete re-epithelialization occurring after 2 months. In case 2, a 58-year-old woman with a history of hemorrhoids developed painful PAUs while using an antihemorrhoidal ointment for 2 months. No other probable cause was found, and the ulcers were treated by discontinuing the ointment. The ulcers showed marked improvement, and complete re-epithelialization occurred after 6 weeks without additional treatment.

RESUMEN

Materials and Methods: In a research experiment, 48 male Wistar rats were anesthetized and second-degree burns were induced on their backs. The rats' wounds were then uniformly inoculated with MRSA. Various treatments were applied to the burn wounds daily, including Myrtus ointment, silver nanoparticles, silver nanoparticles-Myrtus ointment, silver sulfadiazine-Myrtus ointment, silver sulfadiazine 1%, mupirocin ointment, and a positive control. The study measured the antimicrobial effects, wound area, percentage of wound healing, antioxidant capacities, malondialdehyde, and nitric oxide concentrations in the serum of the rats. Data analysis was performed using GraphPad software, with one-way ANOVA and Tukey's tests used to determine the statistical significance of the results. Results: Rats treated with Myrtus ointment, silver nanoparticles-Myrtus ointment, and mupirocin had reduced bacterial growth compared to the positive control group, nanoparticle ointment, and silver sulfadiazine (P < 0.05). The wound area of the Myrtus ointment group decreased significantly on the seventh and fourteenth days, as well as the level of MDA and nitric oxide, compared to the other groups. In Myrtus and silver sulfadiazine-Myrtus ointment increased the thickness of the epidermis and dermis compared to the other groups. Conclusion: Based on the anti-inflammatory, antimicrobial, and wound healing properties of Myrtus, with further studies, an ointment of this plant may be used as a main or complementary treatment for burn wound infections caused by MRSA.

RESUMEN

BACKGROUND: Hypertrophic scars (HS) are a common disfiguring condition in daily clinical encounters which brings a lot of anxieties and concerns to patients, but the treatment options of HS are limited. Black cloth ointment (BCO), as a cosmetic ointment applicable to facial scars, has shown promising therapeutic effects for facial scarring. However, the molecular mechanisms underlying its therapeutic effects remain unclear. MATERIAL AND METHODS: Network pharmacology was first applied to analyze the major active components of BCO and the related signaling pathways. Subsequently, rabbit ear scar model was successfully established to determine the pharmacological effects of BCO and its active component ß-elemene on HS. Finally, the molecular mechanism of BCO and ß-elemene was analyzed by Western blot. RESULTS: Through the network pharmacology, it showed that ß-elemene was the main active ingredient of BCO, and it could significantly improve the pathological structure of HS and reduce collagen deposition. BCO and ß-elemene could increase the expression of ER stress-related markers and promote the increase of apoptotic proteins in the Western blot experiment and induce the apoptosis of myofibroblasts. CONCLUSIONS: Our findings indicate that the material basis for the scar-improving effects of the BCO is ß-elemene, and cellular apoptosis is the key mechanism through which the BCO and ß-elemene exert their effects.

RESUMEN

Symblepharon is an adverse ocular disease resulting in ocular discomfort and impaired vision, severely dragging down a patient's quality of life. Due to the specificity of the ocular surface, the retention time of drugs on it is short, leading to limited therapeutic effects for ocular diseases. Therefore, it is imperative to design a novel drug delivery system, which can not only prolong the retention time of a drug but also play an anti-fibrosis role in symblepharon. Herein, an antifouling supramolecular polymer ophthalmic ointment consisting of poly(N-acryloyl alaninamide) (PNAAA), vitamin C (VitC) and levofloxacin (Levo) was developed (termed PNAVL ophthalmic ointment), which acted as a mucoadhesive and long-acting ocular delivery system. This antifouling PNAVL ophthalmic ointment improved the retention time of VitC and Levo, and simultaneously provided anti-inflammation and anti-fibrosis effects for mitigating symblepharon after ocular alkali burn injury.

RESUMEN

BACKGROUND: Vitiligo remains a challenging condition to treat. Fire needle therapy, a traditional Chinese medicine technique, has potential as an alternative therapeutic strategy. However, rigorous evidence on its efficacy is lacking. OBJECTIVE: We aimed to evaluate the efficacy and safety of fire needle therapy, alone and combined with topical tacrolimus ointment, for non-segmental stable vitiligo. METHODS: In this 6-month randomized self-controlled trial, 35 vitiligo patients were enrolled, providing three similar lesions each. Lesions were randomly allocated to receive fire needle monotherapy, 0.1% tacrolimus ointment monotherapy, or combined fire needle and tacrolimus ointment therapy. The main outcome was change in vitiligo surface area. RESULTS: In total, 29 patients completed the 6-month follow-up. The combination therapy group showed significantly greater reductions in vitiligo surface area compared to monotherapy groups starting at months 4 and 5. By the end of the study, combination therapy resulted in remarkably higher repigmentation responses, with 89.7% of lesions showing at least mild (≥25%) repigmentation and 51.7% showing good (≥50%) repigmentation. This significantly exceeded the outcomes with topical tacrolimus ointment alone, which only achieved 6.9% mild response and 6.9% good response. Fire needle monotherapy also demonstrated steady repigmentation over time, with 69% of lesions attaining a mild response by month 6. Importantly, no major adverse events occurred. CONCLUSION: This study provides promising preliminary evidence supporting the use of fire needle therapy, alone or in combination with topical tacrolimus ointment, for inducing repigmentation in non-segmental stable vitiligo. As a non-pharmacological approach, fire needle therapy warrants further study as an alternative vitiligo treatment.

RESUMEN

The indications for collagenase ointment (CO) and its efficacy are not clearly established in the treatment of second-degree burn wounds. To evaluate the efficacy of CO versus silver sulfadiazine ointment (SSD) in the treatment of second-degree burn wounds. A total of 170 eligible patients with deep second-degree burns, aged 18-65 years, with injuries occurring within 48-96 h, and having a total wound area of less than 30% of the total body surface area were included from 5 centers in China. The primary outcome was the wound healing time, and the secondary outcomes were the clearance time of wound necrotic tissues, wound healing rate, and wound inflammation. The study included 85 patients in SSD group and 84 in CO group in the modified intention-to-treat (mITT) population. The median time of wound healing was comparable in both groups (10 days vs. 10.5 days P = 0.16). The time for wound necrotic tissue removal was significantly shortened by CO compared with SSD (5 vs. 10 days P < 0.01). Wound inflammation, pain, wound healing rate, and scar were compared with SSD (all P-values > 0.05). No adverse events, such as infection or allergic reactions to the drugs and materials used, were reported. Both CO and SSD could heal the burn wounds at 10 days of treatment. However, CO significantly shortened the time of wound necrotic tissue removal by 5 days. Trial Registration: ChiCTR2100046971.

RESUMEN

BACKGROUND: Psoriasis is a common chronic inflammatory skin disorder. Qingxiong ointment (QX) is a natural medicinal combination frequently employed in clinical treatment of psoriasis. However, the active ingredients of QX and its precise mechanisms of improving psoriasis remain unclear. This study elucidated the effects of QX on an Imiquimod (IMQ)-induced mouse model of psoriasis while also exploring the regulation of the active ingredient of QX, shikonin, on the HIF-1 signaling pathway in HaCaT cells. METHODS: A mouse model of psoriasis was established through topical application of IMQ, and the local therapeutic effect of QX was evaluated using dorsal skin tissue with mouse psoriatic lesion and Psoriasis Area Severity Index (PASI) scores, hematoxylin-eosin (HE) staining, and immunohistochemical staining. Elisa and qPCR were employed to identify changes in the expression of inflammation-related factors in the mouse dorsal skin. Immunofluorescence was used to assess changes in the expression of T cell subsets before and after treatment with various doses of QX. HPLC was used to analyze the content of shikonin, and network pharmacology was employed to analyze the main targets of shikonin. Immunofluorescence was used to identify the effects of shikonin on the HIF-1 signaling pathway in IL6-induced psoriasis HaCaT cells. Finally, qPCR was used to identify the differential expression of the HIF-1 signaling pathway in skin tissues. RESULTS: QX significantly reduces PASI scores on the backs of IMQ-induced psoriasis mice. HE staining reveals alleviated epidermal thickness in the QX group. Immunohistochemical analysis shows a significant reduction in ICAM, KI67, and IL17 expression levels in the QX group. Immunofluorescence results indicate that QX can notably decrease the proportions of CD4+ T cells, γδ T cells, and CD8+ T cells while increasing the proportion of Treg cells. Network pharmacology analysis demonstrates that the main targets of shikonin are concentrated in the HIF-1 signaling pathway. Molecular docking results show favorable binding affinity between shikonin and key genes of the HIF-1 signaling pathway. Immunofluorescence results reveal that shikonin significantly reduces p-STAT3, SLC2A1, HIF1α, and NOS2 expression levels. qPCR results show significant downregulation of the HIF-1 signaling pathway at cellular and tissue levels. CONCLUSION: Our study revealed that QX can significantly reduce the dorsal inflammatory response in the IMQ-induced psoriasis mouse model. Furthermore, we discovered that its main component, shikonin, exerts its therapeutic effect by diminishing the HIF-1 signaling pathway in HaCaT cells.

RESUMEN

Addressing the intertwined challenges of antimicrobial resistance and impaired wound healing in diabetic patients, an oil/water emulsion-based nano-ointment integrating phenylpropanoids-Eugenol and Cinnamaldehyde-with positively-charged silver nanoparticles was synthesized. The process began with the synthesis and characterization of nano-silver, aimed at ensuring the effectiveness and safety of the nanoparticles in biological applications. Subsequent experiments determined the minimum inhibitory concentration (MIC) against pathogens such as Streptococcus aureus, Pseudomonas aeruginosa and Candida albicans. These MIC values of all three active leads guided the strategic formulation of an ointment base, which effectively integrated the bioactive components. Evaluations of this nano-ointment revealed enhanced antimicrobial activity against both clinical and reference bacterial strains and it maintained stability after freeze-thaw cycles. Furthermore, the ointment demonstrated superior in-vitro diabetic wound healing capabilities and significantly promoted angiogenesis, as shown by enhanced blood vessel formation in the Chorioallantoic Membrane assay. These findings underscore the formulation's therapeutic potential, marking a significant advance in the use of nanotechnology for topical wound care.

RESUMEN

Ophthalmic diseases can result in permanent vision loss and blindness. Convenient topical and systemic treatments are preferred to address these sight-threatening conditions. However, the unique anatomy of the eye presents challenges for drug delivery. Various ophthalmic ointment formulations have been developed to enhance bioavailability in the eye to prolong residence time and improve corneal permeability. This article explores a wide range of ocular diseases affecting individuals globally and how ointments are used to manage them. From eye to ocular barriers, this review focuses on published scientific research and formulation strategies for severe ocular complications using conventional topical ointments. Additionally, it delves through patented technologies and marketed formulations supporting the use of ointments in ocular drug delivery.


Eye illnesses can cause blindness. The treatment is tricky due to eye's complex makeup. This paper talks about eye ointments also known as 'creams' or 'pomades' used to deliver medicine to the eye. These creams make the medicine work better by staying in the eye longer and absorbing faster. The present work looks at different eye problems and talks about ointments used to treat both internal and external eye diseases. It also explains how the eye is built and why it is hard for medicine to get in. There is also an information about ointments that have been discovered with some new ideas and those available in the market to cure eye problems.
